Abstract

An electronic cigarette includes a shell and a mouthpiece. The external wall of the shell has an air inlet. An atomizer and a liquid-supply are in contact with each other. The air inlet, atomizer, an aerosol passage, and a mouthpiece are sequentially interconnected.

Claims (34)

1. An electronic cigarette, comprising:

a housing having an inlet and an outlet;

a liquid storage body in the housing holding a liquid;

an air flow path through the housing; and

an atomizer in the housing between the inlet and the outlet including:

a porous body in contact with the liquid storage body; and

a heating wire in the atomizer surrounded by the porous body.

2. The electronic cigarette of claim 1 with the liquid storage body including fiber material.

3. The electronic cigarette of claim 1 wherein the housing comprises a cylindrical tube having a central axis and the heating wire extending in a direction substantially perpendicular to the central axis.

4. The electronic cigarette of claim 1 further including a battery, a sensor and an electronic circuit board within the housing, with the circuit board electrically connected to the battery, the sensor and the heating wire.

5. The electronic cigarette of claim 4 further including a vapor-liquid separator separating the sensor from atomizer and the liquid storage body.

6. The electronic cigarette of claim 5 with the vapor-liquid separator comprising a check valve covering a through hole.

7. The electronic cigarette of claim 5 with the vapor-liquid separator comprising plastic or rubber.

8. The electronic cigarette of claim 1 with air flow channel connecting the inlet to the outlet, and with part of the air flow channel alongside of the liquid storage body.

9. The electronic cigarette of claim 1 with the heating wire comprising a wire coil.

10. The electronic cigarette of claim 1 further including an atomization cavity within the atomizer.

11. The electronic cigarette of claim 1 with the outlet within a mouthpiece that is screwed onto the housing.

12. The electronic cigarette of claim 1 with part of the air flow channel alongside the liquid storage body source.

13. The electronic cigarette of claim 1 wherein the porous body comprises a porous bulge section which projects into the liquid storage body.

14. An electronic cigarette, comprising:

a housing having an inlet and an outlet;

a liquid storage body in the housing holding a liquid;

an air flow path through the housing; and

a porous cylindrical atomizer in the housing between the inlet and the outlet, with the porous cylindrical atomizer in contact with the liquid storage body; and

a heating wire coil within and surrounded by the porous cylindrical atomizer.

15. An electronic cigarette comprising;

a housing having an inlet and an outlet;

an electronic circuit board and an atomizer having a heating element, within the housing;

a battery electrically connected to the electronic circuit board;

a stream passage within the housing leading from the inlet to the atomizer;

a liquid storage body including fiber material in a cylindrical section of the housing, with the liquid storage body in physical contact with the atomizer; and

an aerosol passage from the atomizer to the outlet.

16. The electronic cigarette of claim 15 further including a sensor in the stream passage, with the sensor electrically linked to the electronic circuit board.

17. The electronic cigarette of claim 15 with the heating element comprising a wire coil in a cavity in the atomizer.
